AI Sky replacement - when original sky has clouds
Is is possible to increase the aggressiveness of the sky replacement. I find that if my original sky already has clouds L4 has trouble removing them completely regardless of the Horizon Blending, Global Sky and Local Sky settings. I'm not sure if L4 is deciding these are part of the foreground or just not removing the original clouds completely in the "mask".

@Russ, I'm afraid that if the original sky is overexposed AI will have trouble detecting the sky and carry out the replacement.
@C S, the first iteration of AI Sky replacement mostly targets dull skies without any clouds. Chances are that if the original sky already looks pretty or is too cloudy some of the clouds will not be replaced / overlapped. This is something our team is aware of and thus our devs will keep teaching algorithms to process such photos in a better way.

@Russ, that does look like a possible workaround, but I still notice that the clouds left in your overexposed sky in the left hand sky/land boundary are still present in the AI replacement. I tried something to this effect yesterday, but I left a 20 pixel edge on the foreground and filled the rest with the average of the original sky in the hopes that L4 would replace it correctly, but it didn't and actually thought the boundary was part of the foreground.
I love how L4 can replace around very intricate foregrounds (ie. needles on pine trees, leaves in trees) with better results than manually masking, but it leaves you wanting more when it doesn't replace some existing clouds or introduces a weird glow in the foreground at the sky boundary. It's not perfect at this point because I have found numerous images where it doesn't detect the sky correctly, but it's better than just about anything I have tried and it does it with minimal effort on the images it does work on.
I'm hoping some further learning or tweaking of the algorithm will get this closer to working on all images. Having an option to export the foreground with the sky transparent would be ideal to allow further refinements.

Yes. It's driving me crazy tonite. i still get ghosts of darker parts of the original clouds in the replacement. And if there are branches in the foreground that hang down in the sky area, i can't get it to work at all. Also, does AI Sky Replacement work on Portrait format images?
Excuse my naïveté - I'm a drummer. -
